Seed Structure

Seed structure refers to the physical morphology and developmental characteristics of cannabis seeds, including coat thickness, size variation, and internal anatomy. While not a terpene, seed structure is a critical trait for breeders selecting for viable germination, genetic stability, and plant vigor. Seed coat coloration (often tan, brown, or mottled patterns) and surface texture vary across cultivars and can indicate maturity and viability. Breeders often examine seed structure under magnification to assess seed quality before breeding programs, as healthy seeds with robust structures tend to produce more consistent offspring. Different seed types—regular, feminized, and autoflowering—may display observable structural differences related to their genetic construction and breeding methodology.

Breeders monitor seed structure as a quality-control metric when producing seed stock, as coat integrity and consistent sizing correlate with germination rates and seedling health. Selecting parent plants that produce structurally sound seeds supports reliable breeding outcomes across generations.
